Specification of Letters Patent.

Patented Feb. 20, 1906.

To all whom, it may concern.-

Be it known that I, CHARLES VVILLIAMs, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Mechanical Movements, of 'which the following is a specification.

My invention is concerned with a novel mechanical movement by which I transform the continuous rotary movement of a shaft in one direction into the intermittent rotary movement of the elements to which the power is finally applied, and between the intermittent rotary movements of said elements I give them a reciprocating movement transverse to the rotation thereof.

I have shown my invention in the form in which I employ it in connection with my multicolor-press, application Serial No. 150,563, filed April 1, 1903, and as mounted in a frame suitable for such a press, although it will be understood that it might be otherwise mounted and differently constructed in some respects.

To illustrate my invention, I annex hereto siX sheets of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which Figure 1 is a side elevation of my movement as mounted in a frame and supplied with a heavy driving-pulley. Fig. 2 is a vertical section of the same substantially on the line A A of Fig. 1. Fig. 3 is a sectional view, on an enlarged scale, on the line C O of Fig. 2. Fig. 4 is a sectional view on the line D D of Fig. 2. Fig. 5 is a fragmentary view of a portion of the mechanism shown in Fig. 4, butv -with the parts in a slightly different relative position. Fig. 6 is a side elevation of a portion of the mechanism shown in Fig. 3 as seen from the line E E of said figure. Fig. 7 is a detail in section on the line F F of Fig. 2. Fig. 8 is a sectional view on the line G G of Fig. 7. Fig. 9 is a sectional detail showing the construction of the locking mechanism employed in my movement. Fig. 10 is a side elevation of the same as seen from the right of Fig. 9, and Fig. 11 is a detail of the same in section on the line H H of Fig. 9.

To furnish a suitable support for my novel movement, I have shown the framework consisting of the three standards 20,21, and 22;

They are spaced apart at the bottom of th machine by the transverse pieces 23, extending between the standards and 21, and by the projections or sleeves 24, which unite the standards 21 and 22 and which may be integral with the latter standard. Journaled in the bearings 25 and 26, formed in the tops of the standards 20 and 21, respectively, is the shaft 27, which has frictionally mounted thereon a suitable frame consisting in the embodiment of the invention illustrated of a pair of spiders and 31, spaced apart on the shaft by collars 28 and 29. he shaft 27 has a certain amount of movement independent of the frame provided by the spiders 30 and 3 1,

and as a means of securing an accurate and easily-adjusted alinement I may taper the shaft 27 at the bearing portions 32 and 33, with which the complementarily shaped inner bearing-surfaces of the hubs of the spiders cooperate.

As will be best seen from Fig. 3, the spiders 30 and 31 have five equidistant and symmetrical arms, each opposite pair of which is connected by a rod or bar 34, furnished with the shoulders and nuts, as clearly shown in Fig. 2. In addition to these rigid cross-bars 34 I employ the swinging yoke-shaped members 35, which carry the members to which the movement imparted to the mechanism is finally applied. Where the movement is applied to a multicolor-press, the members 35 will be provided with platens. These swinging yoke shaped members are preferably j ournaled on conical bearing studs 36, as shown, and the enlarged central portion 37, which is the effective part of the member, will be seen to be disposed about half-way between the arms to which it is attached and the adjacent arms.

Fixed onto the shaft 27 inside of the collars 28 and 29 are the bearing plates or disks 38, which have the five equidistant and symmetrical recesses 39 in the periphery thereof to receive the bearing-rods 40, which are rigidly secured in place between said collars by the nuts 41 at their ends. To assist in spacing the collars 38, I preferably form the oppositely-directed shoulders 42 and 43 on the shaft 27, against which the collars 38 abut and where they are held by the bolt' or bearing-rods 40. The bearing-rods are provided with the oppositely-directed conical H v bearingsurfaces 44, facing outward, with which cooperate the complementary bearingapertures in the pairs of bars or links 45 and 46," whijch are also provided atjtheir other ends with bearing-rods 48,"'h"avin'g oppositely directed conical bearing-surfaces 47 formed on the ends thereof, which cooperate with the complementarily-shaped bearing rece'sses in the links or bars 45 and 46. Each rod 48 is supportedand rocks in a bearingi49, projecting upwardly from one of themembers 37, (when in its lowermost position,) s o'that if the parts be in the position shown in Fig.4. and the shaft 27 isf'rocke'd so asto carry the bars or links 45 a a re' to "therad'ial' position shown in.

If now' withf'the members 37 retracted and the parts in the position shown'in Fig.4" the spiders be unlocked, so that'they are free, to move with the shaft 27 and the shaft b' moved forward or clockwise through an angle 0'1" seventy two degrees, therela'tiv'e position 'of the parts shaft 27.

aisles the members 37 outward, it necessary to lock the spiders from rotation and to rotate the shaft 27 backward, which will bring the parts" to the position 'shown' in the fragmen- "t'ary view of Fig. 5', the'lir'nit ofthe outward movement of the member 37 having been reached when half the movement was completed, the'remainder of the movement being devoted to its retraction. The spiders are now unlocked, and the shaft 27 is rotated forwardt'. e., clockwisethrough a space of seventy-two degrees, carrying with it all the parts in the position shown in Fig. 5. At the end of the seventy-two-degree movement the spiders are again locked, and order to throw the members '37 outward agai'n'to cooperatewith their associated elements in the new'positi on it is necessary to rotate the shaft will be apparent that it is necessary, starting with the part's i'n the position Shawn in Fig. 4.,

employ the nie'ohanism'now to be' described.

Referring 'hhw toiFigs. 1, 2, 7, ands, itfwill beseerf that'I apply power through means of a: belt-wheel 53, which is: preferably wai ed to'affly-wheel 54,11) ofwhich' are secnred to a shaftst, nio i ed; torot'ate ina bearin formedfin e "fiamework and carrying on its inner nd a ga'r pinion 56'. This pir i nte meshes'with the'peripheral ear tee'th 57- of a Wheel: or disk' 58; which wil [thus be seen to ,be 'in"continual ro'tationffThis disk 58 is looselymounted, means of the hub 59, on

" the bearing 'f' o'rmed onthe outer side and inner end of the bearing '26 forone end of the The disk 58 is provided on its face with an annulus60, which has at one point of itsinnersurface the seven gear-teeth 61 and substantially diametrically opposite thereto Midway eleven gea r t'ee'th instead of seven. The hub 59 "of th'e'wheel or, disk 58 is'provided' with the mutilated gear '64,'whose eleven teeth are substantially diametrically opposite to the teeth the flange 60 These sets ofge arteeth 61, 62, and 63 are adapted to mesh with a gear-pinion 65 on the under side thereof and rotate it three times in succession, giving it a greater rotation during the intermediate ones than during the two end ones. The gear-teeth 64 engaging it at the upper side give it a rotation in the opposite direction to the same extent as that of the intermediate rotation by the teeth 63. The pinion 65 is formed on the inner end of the horizontal shaft 66, mounted to rotate in the bearings 67 and 68, formed in the upper parts of the frames 21 and 22. The pinion 65 has fourteen teeth thereon, and between the bearings 67 and 68 is formed another pinion 69, having twenty teeth thereon and meshing with the gear-pinion 70, splined on the end of the shaft 27 and having fifty teeth. From a consideration of these ratios it will be apparent that when the teeth 61 and 62, seven each, engage the pinion 65 they will rotate it one hundred and eighty degrees in one direction and that as the gear-pinion 69 has twenty teeth and the gear-pinion 70 fifty teeth these one hundred and eighty degrees of movement of the pinion 65 will serve to advance the pinion 70 through ten of its teeth, or seventy-two degrees, which will be remembered is the amount that the shaft 27 and the spiders must be advanced at every other movement of the shaft 27. By reference to Fig. 7 it will be apparent that when the pinion 65 is engaged by the teeth 61, 62, or 63 it cannot be in engagement with the teeth 64, so that the shaft 27 is rotated in the opposite direction independently of the disk 58 and at a different rate of movement. When the teeth 64 are in engagement with the pinion 65, it will be apparent that while the disk 58 is rotating independently of and at a different rate of speed from the shaft 27 it is rotating in the same direction.

Referring now to Figs. 3, 4, 5, and 7, the sequence of movements of the parts can now be readily seen. With the parts in the position shown in Fig. 3 the gear mechanism is at the same time in the position shown in Fig. 7, the members 37 being thrust out and ready to return by the reverse movement of the shaft 27, caused by the engagement of the teeth 64 with the pinion 65. When the disk 58 has advanced clockwise a suflicient distance to free the pinion from the teeth 64, the members 37 have been retracted and the parts arein the position shown in Fig. 5. As the teeth 62 engage the pinion 65 from the opposite side the spiders are unlocked, and the platens and shaft are advanced through seventy-two degrees to the new position. The parts are still in the relative position shown in Fig. 5. The teeth 63 now engage the pinion 65, the spiders being locked, and cause the printing to be effected and the parts to be moved from the position shown in Fig. 5 to that shown in Fig. 4. The

amount of angular movement given to the shaft 27 during these inward and outward movements of the members 37 is about one hundred and twelve degrees, more angular movement of the shaft 27 being required for this movement than for the advancing of the mechanism as a whole. The amount of the alternate backward or forward movements of the shaft is of course always equal. The teeth 61 now engage the pinion 65, and the spiders being unlocked the whole mechanism is advanced through the seventy-two degrees to the fresh point, the parts being in the position shown in Fig. 4. The teeth 64 now engaging the pinion 65 on the opposite side, the spiders being locked, forces the members 37 outward and inward, the backward movement of the shaft 27 thus changing the position of the parts from that shown in Fig. 4 to Fig. 5.

Mechanism for locking and unlocking the spiders at the proper time will next be explained, reference being had especially to Figs. 8 and 9 to 11. The flange 60 has on its outer periphery a set of gear-teeth 71, twice the number of the gear-teeth constituting the periphery of the gear-wheel 72, with which it meshes. This gearwheel is secured upon the inner end of a shaft 73, mounted in the bearing 74, formed in the standard 21. Secured on the outer end of this shaft 73 is a cam-disk 75, which has frictional engagement with the end of the locking-lever 76, preferably through the antifriction-roller 77, yieldingly mounted in the outer end of said locking-lever. A helically-coiled contractile spring 78, secured on the under side of the lever 76 and to a bracket 79, serves to hold the inner end of the lever down, so that its outer end, carrying the roller 77, will be kept in engagement with the cam-disk. This lever 76 is pivotally mounted in the standard 21, passing through apertures formed therein. The locking edge 80 of said lever cooperates once every revolution of the disk 72 or twice every revolution of the disk 58, which corresponds to the cycle of movement of the mechanism, with a yoke 81 rigidly secured on the outer ends by the arms of the spiders 31 in suitable position to lock them from movement, as is necessary in the operation of the mechanism above described.

It will be apparent that (except for the design of the cam 75 shown) the disk 58 may be driven in either direction and the desired sequence of movements obtained, although with the particular design of cam 75 shown it must always rotate in the direction indicated by the arrows adjacent thereto on the different figures. In the description the word forward has been employed to indicate a. clockwise movement, as appears from the position of the figure under description. As seen from Fig. 1, the disk 58 rotates forward continuously, while the shaft 27 has a cycle of three backward. and one forward movement is backward.

While I have shown and described my ap- ,paratus as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of some modifications and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.
